Enhancing Lower Eyelid Suspension Outcomes Through Pre-surgical Facial Nerve Reanimation: A Comparative Study.

BACKGROUND: Lower eyelid suspension, a common therapeutic procedure for facial paralysis-induced eyelid retraction, faces challenges due to high recurrence in patients lacking facial muscle function and impedes wider adoption. This research aims to explore the potential effects of restoring orbicularis oculi muscle tension through facial nerve reanimation prior to lower eyelid suspension and to define the indications for lower eyelid suspension. METHODS: The study encompassed 32 individuals with complete facial paralysis, segmented into group A (reanimation group) and group B (non-reanimation group), based on whether the orbicularis oculi muscle's tension was restored through facial nerve reconstruction prior to lower eyelid suspension. Subjective assessments of eyelid closure (the inter-eyelid gap upon gentle closure) and objective methods measures of scleral show (the distance from the pupil's center to the lower eyelid margin, MRD2) were used to provide a comprehensive analysis of long-term effectiveness. RESULTS: The group A exhibited significantly greater long-term improvement in lagophthalmos and lower eyelid ectropion. The alterations in MRD2 measured 2.66 ± 0.27 mm in the group A versus 2.08 ± 0.53 mm in the group B, denoting a statistically significant variance (p < 0.001). Moreover, while the ratio of MRD2 preoperative 6 months postoperative revealed no significant difference between groups, a significant difference emerged in 12 months postoperative (group A: 1.02 ± 0.21; group B: 1.18 ± 0.24; p < 0.05), with the values in group A closer to 1, indicative of enhanced symmetry. CONCLUSIONS: Restoring the tension in the orbicularis oculi muscle through facial nerve reconstruction prior to palmaris longus tendon sling could effectively sustain long-term outcomes of lower eyelid retraction correction and reduce the recurrence rate.

Disruption of Zinc Homeostasis by a Novel Platinum(IV)-Terthiophene Complex for Antitumor Immunity.

Zinc homeostatic medicine is of great potential for cancer chemo-immunotherapy; however, there are few reports on antitumor compounds that can trigger Zn2+ -mediated immune responses. In this work, we developed a novel cyclometalated PtIV -terthiophene complex, Pt3, that not only induces DNA damage and cellular metabolism dysregulation, but also disrupts zinc homeostasis as indicated by the abnormal transcriptional level of zinc regulatory proteins, excess accumulation of Zn2+ in cytoplasm, and down-regulation of metallothioneins (MTs), which further caused redox imbalance. The simultaneous disruption of zinc and redox homeostasis in response to Pt3 treatment activated gasdermin-D mediated pyroptosis accompanied by cytoskeleton remodeling, thus releasing pro-inflammatory cytokines to promote dendritic cell (DC) maturation and T cell tumor-infiltration, eventually eliminating both primary and distant tumors in vivo. As far as we know, this is the first metal complex that can regulate zinc homeostasis to activate antitumor immunity.

Self-Amplifying Iridium(III) Photosensitizer for Ferroptosis-Mediated Immunotherapy Against Transferrin Receptor-Overexpressing Cancer.

Photoimmunotherapy is attractive for cancer treatment due to its spatial controllability and sustained responses. This work presents a ferrocene-containing Ir(III) photosensitizer (IrFc1) that can bind with transferrin and be transported into triple-negative breast cancer (TNBC) cells via a transferrin receptor-mediated pathway. When the ferrocene in IrFc1 is oxidized by reactive oxygen species, its capability to photosensitize both type I (electron transfer) and type II (energy transfer) pathways is activated through a self-amplifying process. Upon irradiation, IrFc1 induces the generation of lipid oxidation to cause ferroptosis in TNBC cells, which promotes immunogenic cell death (ICD) under both normoxia and hypoxia. In vivo, IrFc1 treatment elicits a CD8+ T-cell response, which activates ICD in TNBC resulting in enhanced anticancer immunity. In summary, this work reports a small molecule-based photosensitizer with enhanced cancer immunotherapeutic properties by eliciting ferroptosis through a self-amplifying process.

A Carbonic Anhydrase IX (CAIX)-Anchored Rhenium(I) Photosensitizer Evokes Pyroptosis for Enhanced Anti-Tumor Immunity.

An ideal cancer treatment should not only destroy primary tumors but also improve the immunogenicity of the tumor microenvironment to achieve a satisfactory anti-tumor immune effect. We designed a carbonic anhydrase IX (CAIX)-anchored rhenium(I) photosensitizer, named CA-Re, that not only performs type-I and type-II photodynamic therapy (PDT) with high efficiency under hypoxia (nanomolar-level phototoxicity), but also evokes gasdermin D (GSDMD) mediated pyroptotic cell death to effectively stimulate tumor immunogenicity. CA-Re could disrupt and self-report the loss of membrane integrity simultaneously. This promoted the maturation and antigen-presenting ability of dendritic cells (DCs), and fully activated T cells dependent adaptive immune response in vivo, eventually eliminating distant tumors at the same time as destroying primary tumors. To the best of our knowledge, CA-Re is the first metal complex-based pyroptosis inducer.

Ferroptosis-Enhanced Cancer Immunity by a Ferrocene-Appended Iridium(III) Diphosphine Complex.

Ferroptosis is a programmed cell death pathway discovered in recent years, and ferroptosis-inducing agents have great potential as new antitumor candidates. Here, we report a IrIII complex (Ir1) containing a ferrocene-modified diphosphine ligand that localizes in lysosomes. Under the acidic environments of lysosomes, Ir1 can effectively catalyze Fenton-like reaction, produce hydroxyl radicals, induce lipid peroxidation, down-regulate glutathione peroxidase 4, and result in ferroptosis. RNA sequencing analysis shows that Ir1 can significantly affect pathways related to ferroptosis and cancer immunity. Accordingly, Ir1 can induce immunogenic cells death and suppress tumor growth in vitro, regulate T cell activity and immune microenvironments in vivo. In conclusion, we show the potential of small molecules with ferroptosis-inducing capabilities for effective cancer immunotherapy.

Simultaneous Photoactivation of cGAS-STING Pathway and Pyroptosis by Platinum(II) Triphenylamine Complexes for Cancer Immunotherapy.

Activation of the cyclic GMP-AMP synthase-stimulator of the interferon gene (cGAS-STING) pathway is a potent anticancer immunotherapeutic strategy, and the induction of pyroptosis is a feasible way to stimulate the anticancer immune responses. Herein, two PtII complexes (Pt1 and Pt2) were designed as photoactivators of the cGAS-STING pathway. In response to light irradiation, Pt1 and Pt2 could damage mitochondrial/nuclear DNA and the nuclear envelope to activate the cGAS-STING pathway, and concurrently induce pyroptosis in cancer cells, which evoked an intense anticancer immune response in vitro and in vivo. Overall, we present the first photoactivator of the cGAS-STING pathway, which may provide an innovative design strategy for anticancer immunotherapy.

Induction and Monitoring of DNA Phase Separation in Living Cells by a Light-Switching Ruthenium Complex.

Phase separation of DNA is involved in chromatin packing for the regulation of gene transcription. Visualization and manipulation of DNA phase separation in living cells present great challenges. Herein, we present a Ru(II) complex (Ru1) with high DNA binding affinity and DNA "light-switch" behavior that can induce and monitor DNA phase separation both in vitro and in living cells. Molecular dynamics simulations indicate that the two phen-PPh3 ligands with positively charged lipophilic triphenylphosphine substituents and flexible long alkyl chains in Ru1 play essential roles in the formation of multivalent binding forces between DNA molecules to induce DNA phase separation. Importantly, the unique environmental sensitive emission property of Ru1 enables direct visualization of the dynamic process of DNA phase separation in living cells by two-photon phosphorescent lifetime imaging. Moreover, Ru1 can change the gene expression pattern by modulating chromatin accessibility as demonstrated by integrating RNA-sequencing and transposase-accessible chromatin with high-throughput sequencing. In all, we present here the first small-molecule-based tracer and modulator of DNA phase separation in living cells and elucidate its impact on the chromatin state and transcriptome.

[Trend in the prevalence of prostate cancer in Shihezi, Xinjiang from 2009 to 2017].

OBJECTIVE: To analyze the trend in the prevalence and mortality of prostate cancer in Shihezi, Xinjiang from 2009 to 2017 and provide some evidence for the prevention and control of the malignance. METHODS: We collected the data on the cancer registries in the Shihezi area between 2009 and 2017, calculated the incidence and mortality rates of prostate cancer, and analyzed the annual percent change (APC) and prevalence trend of the disease. RESULTS: The crude incidence rate, age-standardized incidence rate by Chinese standard population (ASIRC), age-standardized incidence rate by world standard population (ASIRW) and cumulative incidence rate of prostate cancer (in 0－74-year-olds) in Shihezi between 2009 and 2017 were 16.94, 10.33, 8.98 and 2.29 per 100 000, respectively. The crude mortality rate, age-standardized mortality rate by Chinese standard population (ASMRC), age-standardized mortality rate by world standard population (ASMRW) and cumulative incidence rate (in 0－74-year-olds) were 9.03, 5.39 and 4.72 and 0.49 per 100 000, respectively. Both the incidence and mortality rates showed an increasing trend from 2009 to 2017, with an APC of 16.69% (P < 0.05) and 19.71% (P < 0.05), respectively. From 2011 to 2017, the increase rates of incidence and mortality of prostate cancer in the >60-year-olds were 86.20% and 89.30%, with the peak values shifted from the 70－74 to the 80－84 years old males. CONCLUSIONS: The incidence and mortality of prostate cancer in Shihezi showed an increasing trend from 2009 to 2017, chiefly in the males aged over 60 years, with the peak value moving towards an older age.

Hand Rejuvenation by Targeted Volume Restoration of the Dorsal Fat Compartments.

BACKGROUND: Recent anatomic findings suggest aging-related changes of the complex fat distribution in the hand. OBJECTIVES: To rejuvenate the aging hand, we developed a targeted fat grafting technique based on the physiologic fat distribution of the hand. METHODS: The dorsum of both hands was examined in 30 healthy volunteers of different age utilizing B-mode ultrasound to determine physiological changes of the aging hand. Additional anatomic dissection was performed in 10 hands of five fresh cadavers to establish the anatomic basis for the targeted restoration technique. A total of 17 patients were treated for hand rejuvenation utilizing this technique and followed up for at least 6 months. The posttreatment outcome was assessed through B-mode ultrasound, 3-dimensional (3D) topography scanning, and a patient satisfaction survey. RESULTS: According to the fat distribution of the dorsum, hand aging was divided into three grades: (1) mild atrophy with rhytides; (2) moderate atrophy with exposed veins; and (3) serious atrophy with exposed tendons. Anatomic findings showed the existence of distinct superficial and deep fat compartments. The average fat grafting volume was 25.5 ml per hand dorsum administered in one or two procedures. Patients were monitored for 8.3 ± 2.6 months. After 6 months, a volume gain was found in all patients. The degree of aging was significantly reduced. The majority of patients (94.1%) were satisfied with their results. CONCLUSIONS: This study provides the anatomic and clinical basis for targeted restoration of the physiological fat volume in the hand dorsum with high satisfaction rates. LEVEL OF EVIDENCE: 4.

Identification of mitochondrial ATP synthase as the cellular target of Ru-polypyridyl-ß-carboline complexes by affinity-based protein profiling.

Ruthenium polypyridyl complexes are promising anticancer candidates, while their cellular targets have rarely been identified, which limits their clinical application. Herein, we design a series of Ru(II) polypyridyl complexes containing bioactive ß-carboline derivatives as ligands for anticancer evaluation, among which Ru5 shows suitable lipophilicity, high aqueous solubility, relatively high anticancer activity and cancer cell selectivity. The subsequent utilization of a photo-clickable probe, Ru5a, serves to validate the significance of ATP synthase as a crucial target for Ru5 through photoaffinity-based protein profiling. Ru5 accumulates in mitochondria, impairs mitochondrial functions and induces mitophagy and ferroptosis. Combined analysis of mitochondrial proteomics and RNA-sequencing shows that Ru5 significantly downregulates the expression of the chloride channel protein, and influences genes related to ferroptosis and epithelial-to-mesenchymal transition. Finally, we prove that Ru5 exhibits higher anticancer efficacy than cisplatin in vivo. We firstly identify the molecular targets of ruthenium polypyridyl complexes using a photo-click proteomic method coupled with a multiomics approach, which provides an innovative strategy to elucidate the anticancer mechanisms of metallo-anticancer candidates.

Facial Symmetry Enhancement and Brain Network Modifications in Surgical Facial Palsy Patients After BoNT-A Treatment on the Unaffected Side.

BACKGROUND: Facial palsy, often resulting from trauma or iatrogenic treatments, leads to significant esthetic and functional impairment. Surgical interventions, such as masseteric-to-facial nerve transfer combined with static suspension, are frequently recommended to restore facial nerve function and symmetry. METHODS: This study examines how Botulinum Toxin A (BoNT-A) treatment on the unaffected side affects facial symmetry and brain connectivity in patients with severe oral commissure droop from facial nerve damage. Patients were divided into two groups: one received BoNT-A injections on the unaffected side, and the other did not. RESULTS: Our findings revealed that BoNT-A treatment not only improved facial symmetry but also induced significant modifications in brain functional network connectivity. These modifications extended beyond the sensorimotor network, involving high-level cognitive processes, and exhibited a significant correlation with the degree of facial asymmetry. CONCLUSIONS: These results provide valuable insights into the mechanisms underlying the positive effects of BoNT-A intervention on motor recovery and brain plasticity in facial palsy patients. Furthermore, the study emphasizes the importance of a multidisciplinary approach to facial palsy rehabilitation. Understanding these intricate interactions between facial symmetry restoration and brain network adaptations may pave the way for more effective treatments and improved quality of life for individuals dealing with facial palsy.

Natural Acceptor of Coumarin-Isomerized Red-Emissive BioAIEgen for Monitoring Cu2+ Concentration in Live Cells via FLIM.

Artificial aggregation-induced emission luminogens (AIEgens) have flourished in bio-applications with the development of synthetic chemistry, which however are plagued by issues like singularity in structures and non-renewability. The unique structures and renewability of biomass moieties can compensate for these drawbacks, but their properties are hard to design and regulate due to their confined structures. Therefore, it appears to be a reasonable approach to derive AIEgens from abundant biomass (BioAIEgens), integrating the bilateral advantages of both synthetic and natural AIEgens. In this work, the blue-violet emissive coumarin with its lactone structure serving as a rare natural acceptor, is utilized to construct donor-π-acceptor typed BioAIE isomers incorporating the propeller-like and electron-donating triphenylamine (TPA) unit. The results show that Cm-p-TPA undergoes charge transfer with its keto form, emitting red light at 600 nm, which can be applied to monitor Cu2+ concentration during mitophagy using fluorescence lifetime imaging microscopy because of the excellent biocompatibility, photostability, and specific recognition to Cu2+ . This work not only demonstrates the feasibility of utilizing positional isomerization to modulate excited-state evolutions and resultant optical properties, but also provides evidence for the rationality of constructing biologically-active BioAIEgens via a biomass-derivatization concept.

Self-assembly of a ruthenium-based cGAS-STING photoactivator for carrier-free cancer immunotherapy.

The cGAS (cyclic GMP-AMP synthase)-STING (stimulator of interferon genes) pathway promotes antitumor immune responses by sensing cytosolic DNA fragments leaked from nucleus and mitochondria. Herein, we designed a highly charged ruthenium photosensitizer (Ru1) with a ß-carboline alkaloid derivative as the ligand for photo-activating of the cGAS-STING pathway. Due to the formation of multiple non-covalent intermolecular interactions, Ru1 can self-assemble into carrier-free nanoparticles (NPs). By incorporating the triphenylphosphine substituents, Ru1 can target and photo-damage mitochondrial DNA (mtDNA) to cause the cytoplasmic DNA leakage to activate the cGAS-STING pathway. Finally, Ru1 NPs show potent antitumor effects and elicit intense immune responses in vivo. In conclusion, we report the first self-assembling mtDNA-targeted photosensitizer, which can effectively activate the cGAS-STING pathway, thus providing innovations for the design of new photo-immunotherapeutic agents.

Multi-site isomerization of synergistically regulated stimuli-responsive AIE materials toward multi-level decryption.

Stimuli-responsive aggregation-induced emission (AIE) materials are highly sensitive and rapidly responsive to external signals, making them ideal solid materials for anti-counterfeiting encryption. However, the limited conformational and packing variations resulting from regio-isomerization with a single substituent restricts the stimuli-responsive behavior of these materials. In this work, several AIE-active regio-structural isomers based on the salicylaldehyde Schiff base scaffold have been straightforwardly obtained through multiple substitutions with bromide and triphenylamine moieties. Solvent-effect experiments demonstrate their different orders of charge-transfer and excited-state intramolecular proton transfer upon photoexcitation, indicating the regulation of excited-state processes via multi-site isomerization. These isomers also demonstrate mechanochromism and acidichromism, allowing for adjustable stimuli-responsive effects. As a demonstration, p-Br-TPA with both mechanochromism and acidichromism can be synergistically utilized for multi-level decryption. This study successfully regulates the evolution of excited states through multi-site isomerization, offering a general approach for achieving tunable stimuli-responsive properties in AIE-active salicylaldehyde Schiff bases toward multi-level decryption.

Room Temperature Phosphorescent Nanofiber Membranes by Bio-Fermentation.

Stimuli-responsive materials exhibiting exceptional room temperature phosphorescence (RTP) hold promise for emerging technologies. However, constructing such systems in a sustainable, scalable, and processable manner remains challenging. This work reports a bio-inspired strategy to develop RTP nanofiber materials using bacterial cellulose (BC) via bio-fermentation. The green fabrication process, high biocompatibility, non-toxicity, and abundant hydroxyl groups make BC an ideal biopolymer for constructing durable and stimuli-responsive RTP materials. Remarkable RTP performance is observed with long lifetimes of up to 1636.79 ms at room temperature. Moreover, moisture can repeatedly quench and activate phosphorescence in a dynamic and tunable fashion by disrupting cellulose rigidity and permeability. With capabilities for repeatable moisture-sensitive phosphorescence, these materials are highly suitable for applications such as anti-counterfeiting and information encryption. This pioneering bio-derived approach provides a reliable and sustainable blueprint for constructing dynamic, scalable, and processable RTP materials beyond synthetic polymers.

[Effects of soothing liver and invigorating spleen recipes on the mRNA and protein expression of TLR4 in hepatic tissues of rats with NASH].

OBJECTIVE: To research the effects of soothing liver and invigorating spleen recipes on expression of TLR4 mRNA and protein expression in hepatic tissue of rats with non-alcoholic steatohepatitis and its mechanism. METHODS: 72 male SD rats were randomly divided into 8 groups: normal group, model group, high-dose soothing liver group (receiving gavage of Chaihu Shugan Powder 9. 6 g/kg), low-dose soothing liver group (receiving gavage of Chaihu Shugan Powder 3.2 g/kg), high-dose invigorating spleen group (receiving gavage of Shen Ling Baizhu Powder 30 g/kg), low-dose invigorating spleen group (receiving gavage of Shen Ling Baizhu Powder 10 g/kg), high-dose integrated Group (receiving gavage of Chaihu Shugan Powder and Shen Ling Baizhu Powder combination recipes 39.6 g/kg), low-dose integrated Group (receiving gavage of Chaihu Shugan Powder and Shen Ling Baizhu Powder combination recipes 13.2 g/kg), 9 rats were in each group. Used high fat diet (10 mL/kg) to establish experiment model of NASH rat. At the end of the sixteenth weeks, the levels of serum lipids, liver lipids and serum aminotransferase were measured by automatic biochemical analyzer; Liver pathology was analyzed by HE and Oil red O staining; TLR4 mRNA was assayed by real-time fluorescent quantitative polymerase chain reaction (RT Q-PCR); TLR4 protein was detected by Western blot. RESULTS: Compared with normal group, the levels of TC, LDL-C in the serum, TC,TG as well as the expression of TLR4 mRNA and protein in the hepatic tissue were dramatically increased in model group (P < 0.01). Compared with the model group, the levels of serum lipids, liver lipids, the expression of TLR4 mRNA and protein in the hepatic tissue were decreased in each treatment group (P < 0.05 or P < 0.01). CONCLUSION: Soothing liver and invigorating spleen recipes can inhibit hepatic TLR4 expression, that may be one of their therapeutic mechanisms. There is much difference between high-does and low-does treatment groups in various testing items, which shows that there is does-effect relationship in intervention NASH.

Metals and inorganic molecules in regulating protein and nucleic acid phase separation.

The realization that liquid-liquid phase separation (LLPS) underlies the formation of membraneless compartments in cells has motivated efforts to modulate the condensation process of biomolecules. Increasing evidence shows that metals and inorganic molecules abundantly distributed in cells play important roles in the regulation of biomolecular condensation. Herein, we briefly reviewed the background of biomacromolecular phase separation and summarized the recent research progress on the roles of metals and inorganic molecules in regulating protein and nucleic acid phase separation in vitro and in cells.

Deep learning-based lung sound analysis for intelligent stethoscope.

Auscultation is crucial for the diagnosis of respiratory system diseases. However, traditional stethoscopes have inherent limitations, such as inter-listener variability and subjectivity, and they cannot record respiratory sounds for offline/retrospective diagnosis or remote prescriptions in telemedicine. The emergence of digital stethoscopes has overcome these limitations by allowing physicians to store and share respiratory sounds for consultation and education. On this basis, machine learning, particularly deep learning, enables the fully-automatic analysis of lung sounds that may pave the way for intelligent stethoscopes. This review thus aims to provide a comprehensive overview of deep learning algorithms used for lung sound analysis to emphasize the significance of artificial intelligence (AI) in this field. We focus on each component of deep learning-based lung sound analysis systems, including the task categories, public datasets, denoising methods, and, most importantly, existing deep learning methods, i.e., the state-of-the-art approaches to convert lung sounds into two-dimensional (2D) spectrograms and use convolutional neural networks for the end-to-end recognition of respiratory diseases or abnormal lung sounds. Additionally, this review highlights current challenges in this field, including the variety of devices, noise sensitivity, and poor interpretability of deep models. To address the poor reproducibility and variety of deep learning in this field, this review also provides a scalable and flexible open-source framework that aims to standardize the algorithmic workflow and provide a solid basis for replication and future extension: https://github.com/contactless-healthcare/Deep-Learning-for-Lung-Sound-Analysis .

Activation of the cGAS-STING pathway by a mitochondrial DNA-targeted emissive rhodium(iii) metallointercalator.

The cyclic GMP-AMP synthase (cGAS)-stimulator of interferon (STING) pathway is a key mediator of innate immunity involved in cancer development and treatment. The roles of mitochondrial DNA (mtDNA) in cancer immunotherapy have gradually emerged. Herein, we report a highly emissive rhodium(iii) complex (Rh-Mito) as the mtDNA intercalator. Rh-Mito can specifically bind to mtDNA to cause the cytoplasmic release of mtDNA fragments to activate the cGAS-STING pathway. Moreover, Rh-Mito activates the mitochondrial retrograde signaling by disturbing the key metabolites involved in epigenetic modifications, which alters the nuclear genome methylation landscape to influence the expression of genes related to immune signaling pathways. Finally, we demonstrate that ferritin-encapsulated Rh-Mito elicits potent anticancer activities and evokes intense immune responses in vivo by intravenous injection. Overall, we report for the first time that small molecules targeting mtDNA can activate the cGAS-STING pathway, which gives insights into the development of biomacromolecule-targeted immunotherapeutic agents.

Multi-Stimuli-Responsive and Cell Membrane Camouflaged Aggregation-Induced Emission Nanogels for Precise Chemo-photothermal Synergistic Therapy of Tumors.

Targeted and controllable drug release at lesion sites with the aid of visual navigation in real-time is of great significance for precise theranostics of cancers. Benefiting from the marvelous features (e.g., bright emission and phototheranostic effects in aggregates) of aggregation-induced emission (AIE) materials, constructing AIE-based multifunctional nanocarriers that act as all-arounders to integrate multimodalities for precise theranostics is highly desirable. Here, an intelligent nanoplatform (P-TN-Dox@CM) with homologous targeting, controllable drug release, and in vivo dual-modal imaging for precise chemo-photothermal synergistic therapy is proposed. AIE photothermic agent (TN) and anticancer drug (Dox) are encapsulated in thermo-/pH-responsive nanogels (PNA), and the tumor cell membranes are camouflaged onto the surface of nanogels. Active targeting can be realized through homologous effects derived from source tumor cell membranes, which advantageously elevates the specific drug delivery to tumor sites. After being engulfed into tumor cells, the nanogels exhibit a burst drug release at low pH. The near-infrared (NIR) photoinduced local hyperthermia can activate severe cytotoxicity and further accelerate drug release, thus generating enhanced synergistic chemo-photothermal therapy to thoroughly eradicate tumors. Moreover, P-TN-Dox@CM nanogels could achieve NIR-fluorescence/photothermal dual-modal imaging to monitor the dynamic distribution of therapeutics in real-time. This work highlights the great potential of smart P-TN-Dox@CM nanogels as a versatile nanoplatform to integrate multimodalities for precise chemo-photothermal synergistic therapy in combating cancers.
